What is the BH curve of a cylinder shape magnet?
Dec 05, 2025| What is the BH curve of a cylinder shape magnet?
As a trusted supplier of Cylinder Shape Magnets, I've often been asked about the BH curve of these magnets. Understanding the BH curve is crucial for anyone involved in the design, selection, or application of cylinder shape magnets. In this blog post, I'll explain what the BH curve is, why it matters, and how it relates to our cylinder shape magnets.
What is the BH Curve?
The BH curve, also known as the magnetization curve or hysteresis loop, is a graphical representation of the relationship between the magnetic flux density (B) and the magnetic field strength (H) in a magnetic material. It shows how the material responds to an applied magnetic field and how it retains its magnetization after the field is removed.


The BH curve is typically plotted on a graph with the magnetic field strength (H) on the x-axis and the magnetic flux density (B) on the y-axis. The curve starts at the origin (0,0), indicating that when there is no applied magnetic field, the magnetic flux density is zero. As the magnetic field strength increases, the magnetic flux density also increases, following a non-linear path.
The shape of the BH curve depends on the properties of the magnetic material, such as its composition, crystal structure, and temperature. Different materials have different BH curves, which can be used to characterize their magnetic properties.
Why is the BH Curve Important?
The BH curve is important for several reasons:
- Magnetic Material Selection: The BH curve provides valuable information about the magnetic properties of a material, such as its saturation magnetization, remanence, and coercivity. This information can be used to select the appropriate magnetic material for a specific application.
- Magnet Design: The BH curve can be used to design magnets with specific magnetic properties. By understanding the relationship between the magnetic field strength and the magnetic flux density, engineers can optimize the shape, size, and orientation of the magnet to achieve the desired performance.
- Magnet Performance Evaluation: The BH curve can be used to evaluate the performance of a magnet. By measuring the magnetic flux density and the magnetic field strength at different points on the curve, engineers can determine the magnet's efficiency, stability, and reliability.
- Magnet Application: The BH curve can be used to predict the behavior of a magnet in a specific application. By understanding the magnetic properties of the material, engineers can design magnetic circuits and systems that are optimized for the application.
BH Curve of Cylinder Shape Magnets
Cylinder shape magnets are widely used in various applications, such as motors, generators, sensors, and magnetic separators. The BH curve of a cylinder shape magnet depends on several factors, such as the material, the size, the shape, and the orientation of the magnet.
In general, the BH curve of a cylinder shape magnet is similar to that of other magnetic materials. It starts at the origin and follows a non-linear path as the magnetic field strength increases. The shape of the curve depends on the properties of the magnetic material, such as its saturation magnetization, remanence, and coercivity.
One of the advantages of cylinder shape magnets is that they can be easily magnetized in a specific direction. By applying a magnetic field in the desired direction, the magnetic moments of the atoms in the magnet can be aligned, resulting in a strong magnetic field. The BH curve of a cylinder shape magnet can be used to optimize the magnetization process and to ensure that the magnet has the desired magnetic properties.
